By default, the Eaglefire receiver utilizes a Picatinny rail system. It can accept an optic attachment and a rear sight attachment, as long as they are compatible with the rail system. It also consists of two essential modular components: the barrel, and the handguard. Although available, the stock component is not necessary.

Its standard modular components include the Performance Barrel, Quadrail Picatinny handguard, and Stock. These components allow for an increased variety of attachments than offered to the receiver alone.
